My Wife and I both have Droids on the same account. I use Google Voice she doesn't. We don't have friends and family so my GV number is not on F&F

1. If I call her using the GV android app and my GV number shows up on her caller ID is the call mobile to mobile or do we both get charged regular minutes?

2. If she calls my GV number and I answer it with my Droid and her Verizon number shows up on my Caller ID is the call mobile to mobile or do we both get charged regular minutes?

Right now I'm not using GV to call my wife but I would like to be able to make all calls with GV without having to worry about using regular minutes when it could be mobile to mobile. I'd really like to hear from a CSR on this.
